Laser Marking

MLPC provides laser marking, laser engraving, and laser etching services as a finishing step in your supply chain.

Laser Marking

Laser marking uses a focused laser beam to modify the surface of a metal, polymer, or plastic to permanently identify, label, or decorate per the customer requirement. This process is used as a more permanent alternative to pad printing, hot stamping, mechanical engraving, silk screening, and chemical etching. Laser marking is a general term used to reference the three processes described below.

Laser Engraving

The process is similar to mechanical engraving, but uses a focus laser beam to remove the material. The maximum engraving depth is typically 0.020" in metals, but can go as deep as 0.125" in materials such as graphite. Laser engraving is generally used when the part is expected to experience high wear. The process is also routinely used to engrave serial numbers and logos into plastic injection molds.

Laser Dark Marking

The process uses a focused laser beam to locally oxidize a metal part leaving a high contrast surface mark. This type of mark is generally done on stainless steel and titanium. MLPC has expertise in using this process on medical parts that will subsequently undergo passivation and autoclave.

Laser Etching

The process is similar to laser engraving but removes 0.001" or less material. The process can be used on bare, anodized, or plated metal surfaces. The process can also be used on polymers and ceramics.

As shown below MLPC can provide value from prototype to production. MLPC prides itself in providing 2-3 day around on most lots of parts. For examples of laser marking applications please click on the images to the right.
